Re: [libvirt] [PATCH 0/1] Bug: Sandbox: libvirt breakdowns qemu guest

1. Problem Description
======================
If QEMU is built without seccomp support, 'elevatorprivileges' remains compiled.
This option of sandbox is treated as an indication for seccomp blacklist support
in libvirt. This behavior is introduced by the libvirt commits 31ca6a5 and
3527f9d. It would make libvirt build wrong QEMU cmdline, and then the guest
startup would fail.
Adding libvirt list.
This would still fail with older QEMUs, so the question is if we should also OR instead
change something in libvirt.
2. Libvirt Log
==============
qemu-system-s390x: -sandbox on,obsolete=deny,elevateprivileges=deny,spawn=deny,\
resourcecontrol=deny: seccomp support is disabled
3. Fixup
========
Wrap the options except 'enable' for qemu_sandbox_opts by CONFIG_SECCOMP.
